Abstract

1. Spayring nozzle head with at least one spraying nozzle and with an electrical heating arrangement, characterized in that there is additionally provided a non-return valve (4) opening towards the spraying nozzle (10) and connected with a heat conduction block (12) against which block there abuts a heating element (PTC element 13) of the electrical heating arrangement, said block at the same time being constructed for heating the spayring nozzle (10).

Description

Die Erfindung bezieht sich auf einen Spritzdüsenkopf mat zumlndest einer Sprizduse und einer elektrischen Heizung. [in solcher Sprjtzdüsertkopf ist beispielswelse in der DE-AS 24 34 491 beschrieben und kann Teil einer Scheibenwaschanlage oder einer Scheinwerferviaschanlaoe sein.The invention relates to a spray nozzle mat at least a spray nozzle and an electric heater. [In such a spray nozzle head, for example, is described in DE-AS 24 34 491 and can be part of a windshield washer system or a headlight washer system.

Die elektrische Beheizung des Spritzdüsenkopfes ist sinnvoll, da erfahrungsgemäß Spritzdüsenköpfe in Winter zur Eanfrierer neigen und die Scheibenwaschanlage oder Scheinwerferwaschanlane dadurch unbrauchbar wird. Um zu erreichen, daß nach der Eanschalten der Scheibenwaschanlage unverzuglach basser aus den Spritzdüsen spritzt, muß durch ean Ruelschiagvental in der Wasserzuführleitung sichergestellt werden, daß bei nicht benutzter Scheibenwaschanlage die Wasserzuführleitung nicht leerlaufen kann. Deshalb ordnet man bei Scheibenwaschanlagen dort, wo sich die Wasserzuführleitung zu den einzelnen Spritzdüsenköpfen verzweigt, ein Rückschlagventil an. Bei Sctierferwaschanlagen muß ein Rückschlagventil unmittelbar vor der Spritzdüse vorgesehen werden, weil diese tiefer liegt als der Wasservorrdtsbehälter und ohne Rückschlagventil der Wasseuorratsbehälter nach einer Betätigung der Scheinwerferwaschanlage von selbst leerlaufen würde.The electrical heating of the spray nozzle head makes sense, since experience has shown that spray nozzle heads tend to freeze in winter, making the windscreen washer system or headlamp washer system unusable. In order to ensure that after switching on the windshield washer system, splashes more readily from the spray nozzles, ean Ruelschiagvental in the water supply line must ensure that the water supply line cannot run empty when the windshield washer system is not used. For this reason, a check valve is installed in windscreen washer systems where the water supply line branches to the individual spray nozzle heads. In the case of secondary washing systems, a non-return valve must be provided immediately in front of the spray nozzle, because this is lower than the water reservoir and without a non-return valve the water storage container would automatically empty after the headlight washer system was actuated.

Diese Aufgabe ward erfandungsgemäß dadurch gelöst, daß zusätzlich ein zur Spratzduse hin sffnendes. behelztes Rückschlaoventil vorgesehen ist.According to the invention, this object was achieved in that an opening towards the spray nozzle was also provided. covered return valve is provided.

Durch die erfindungsgemäße Anordnung des Rückschlacventils im Spritzdüsenkopf und durch die Beheizung dieses Rückschlaauentils wird ein Einfrieren des Ruckschlegventils ebenso zuverlässig verhindert wie ein Einfrieren der Spritzdüse. Hiervon abgesehen ist die Gesamtanordnung kostengünstig, da kein separates Rückschjsgventil in die Wasserzuführleitung eingebaut werden muß.The inventive arrangement of the non-return valve in the spray nozzle head and the heating of this non-return valve prevent the non-return valve from freezing as reliably as freeze of the spray nozzle. Apart from this, the overall arrangement is inexpensive since no separate check valve has to be installed in the water supply line.

Im Spritzdüsenkopf genügt die Anordnung einer einzigen Heizung, wenn das Rückschlagventil Verbindung mit einem Wärmeleitblock hat, gegen den ein Heizelement der elektrischen Heizung anliegt und der gleichzeitig zur Erwärmung der Spritzdüse ausgebildet ist. Die Wärme dieser Heizung ward von dem Wärmeleitblock sowohl der Rückschlagventil als auch der Spritzdüse zugeführt.The arrangement of a single heater in the spray nozzle head is sufficient if the check valve is connected to a heat-conducting block against which a heating element of the electric heater rests and which is at the same time designed to heat the spray nozzle. The heat from this heater was supplied from the heat conduction block to both the check valve and the spray nozzle.

Eine andere, vorteilhafte Ausgestaltung der Erfindung besteht darin, daß das Rückschlagventil ein mittels einer Metallfeder in Schließstellung vorgespanntes Klappenventil ist und daß die Metallfeder gegen den Wärmeleitblock anliegt. Bei dieser Ausführungsform leitet die Metallfeder die Warme von Wärmeleitblock zur Ventalklappe.Another advantageous embodiment of the invention is that the check valve is a flap valve biased in the closed position by means of a metal spring and that the metal spring rests against the heat-conducting block. In this embodiment, the Metal spring the heat from the thermal block to the valve flap.

Besonders gut wird die Wärme zur Ventilklappe geleitet, wenn die Metallfeder eine auf der Ventilklappe auflieoende , mit einen Ende zwischen dem Wärmeleitblock und der Ventilklappe einoespannte Blattfeder ist.The heat is conducted particularly well to the valve flap if the metal spring is a leaf spring which rests on the valve flap and is clamped at one end between the heat-conducting block and the valve flap.

Die elektrische Heizurng ist am einfachsten daduurch oebildet , daß das Heizelement ein von einer Schraubendruckfeder in Anlage gegen den Warmelentblock oehaltenes PTC-Element ist.The electrical heating is most simply formed by the fact that the heating element is a PTC element held by a helical compression spring in contact with the heating element block.

Konstruktiv günstig ist es, wenn die Spannungszufuhr des PTC-Elementes über die Schraubendruckfeder erfolgt.It is structurally favorable if the voltage supply of the PTC element takes place via the helical compression spring.

Im Regelfall wird der Spritzdüserikopf von einem Kunststoffteil umkleidet sein, so daß.er auch im montierten Zustand keine Verbindung mit der Fahzeugmasse hat. Der Stromfluß durch das PTC-Element kann dann auf einfache Weise ermöglicht werden, indem der WärmeleitbJock über eine zweite Schraubendruckfeder mit dem anderen Spannungspol Verbindung hat.As a rule, the spray nozzle head will be encased in a plastic part, so that it has no connection to the vehicle mass, even in the assembled state. The current flow through the PTC element can then be made possible in a simple manner by the heat-conducting jock being connected to the other voltage pole via a second helical compression spring.

Eine weitere, vorteilhafte Ausgestaltung der Erfindung besteht darin, daß der Wärmeleitblock einen Teil der Leitung für die Wasserzufuhr zur Spritzdüse bildet und bis nahe zur Spritzdüse reicht. Bei dieser Ausführungs-form gelangt genügend Wärme durch die im Spritzdüsenkopf vorhandene Flüssigkeit und teilweise auch durch das Material des Spritzdüsenkopfes zur Spritzdüse, so daß auch ein rasches Auftauen einer während eines Fahrzeugstillstandes eingefrorenen Spritzdüse gewährleistet ist.Another advantageous embodiment of the invention is that the heat conduction block forms part of the line for the water supply to the spray nozzle and extends close to the spray nozzle. In this Ausführun g s-shape reaches sufficient heat by the presence in the spray nozzle head liquid and partly by the material of the spray nozzle head to the spray nozzle, so that also rapid thawing is ensured a frozen during vehicle standstill spray nozzle.

ben einer wahlwersen Zufuhr von zwei verschiedenen Flussigkfiten zur Spritzdüsenkopf hat man bisher die einzelnen Zufuhrleitungen schon an einer relativ weit vom Sprtzdusenkopf entfernten Stelle vereinigt und dort das Rückschlagventil angeordnet (DE-OS 30 15 348), so daß die eingangs genannten Nachteile eintreten. Mit verhältnismßig geringem Aufwand lassen sich auch bei einer solchen Zufuhr zweier Flüssigkeiten diese Nachteile vermeiden, wenn der Spritzdüsenkopf zur getrennten Zufuhr zweier Flüssigkeiten ausgebildet und in beiden Flüssigkeitszuleitunqen jeweils ein gegen den Märmeleitblock anliegendes Rückschlagventil vorgesehen ist.ben an optional supply of two different liquids to the spray nozzle head, the individual supply lines have hitherto been combined at a location relatively far from the spray nozzle head and the check valve has been arranged there (DE-OS 30 15 348), so that the disadvantages mentioned at the outset occur. With such a supply of two liquids, these disadvantages can be avoided with relatively little effort if the spray nozzle head is designed for the separate supply of two liquids and a non-return valve is provided in each of the two liquid supply lines.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung dargestellt und wird nachfolgend beschrieben. Die Zeichnung zeigt einen Längsschnitt durch einen erfindungsgemäß gestalteten Spritzdüsenkopf.The invention permits numerous embodiments. To clarify its basic principle, one of these is shown in the drawing and is described below. The drawing shows a longitudinal section through an inventive spray nozzle head.

Die Zeichnung zeigt einen Düsenkörper 1 aus beispielsweise Aluminium, der nach unten hin zwei Anschlußstutzen 2, 3 hat. Über diese Anschlußstutzen 2, 3 können nicht gezeigte Schläuche geschoben werden, durch die der Spritzdüsenkopf Verbindung mit zwei ebenfalls nicht gezeigten Behältern erhält. Für den Anschlußstutzen 3 ist nicht gezeigt, wie dieser mit dem Düsenkörper 1 Verbindung hat und wie von ihm im Spritzdüsenkopf die Flüssigkeitsführung erfolgt, da die Verhältnisse genau wie bei dem anderen Anschlußstutzen 2 sind.The drawing shows a nozzle body 1 made of aluminum, for example, which has two connecting pieces 2, 3 at the bottom. Hoses (not shown) can be pushed over these connecting pieces 2, 3, through which the spray nozzle head is connected to two containers (also not shown). For the connection piece 3 it is not shown how it has a connection to the nozzle body 1 and how the liquid is conducted from it in the spray nozzle head, since the conditions are exactly the same as for the other connection piece 2.

Vom Anschlußstutzen 2 vermag Flüssigkeit durch den Düsenkörper 1 hindurch zu einem Rückschlagventil 4 zu gelangen, welches eine Ventilklappe 5 hat, die von einer Blattfeder 6 in Schließstellung gegen einen Ventilsitz 7 gehalten ist. Öffnet die Ventilklappe 5, so vermag Flüssigkeit in einen Raum 8 und von dort durch eine Zuführleitung 9 hindurch zu einer Spritzdüse 10 zu gelangen, aus der heraus die Flüssigkeit beispielsweise gegen eane Windschutzscheibe spritzt.From the connecting piece 2, liquid can pass through the nozzle body 1 to a check valve 4, which has a valve flap 5, which is held in the closed position by a leaf spring 6 against a valve seat 7. If the valve flap 5 opens, liquid can pass into a space 8 and from there through a feed line 9 to a spray nozzle 10. from which the liquid splashes, for example, against a windscreen.

Die Sprrtzdüse ist ihrerseits in einer Kunststoffkdppe 11 gehalten, die über den Düsenkörper 1 geschoben ist. Um ein Einfrieren der Gesamtanordnung vermeiden zu können, ist innerhalb des Spritzdüsenkopfes ein Wärmeleitblock 12 voroesethen, gegen den ein PTC-Element 13 dadurch anliegt, daß eine Schraubendruckfeder 14 dieses PTC-Element gegen eine Fläctie 15 des Wärmeleitblocks 12 druckt. Die Spannungszufuhr zum FIC-Elenent er folgt mattels eines Kabels 16 und anschließend über die Schraubendruckfeder 14. Auch der andere SpahnungspoJ kann über eine gleiche, nicht dargestellte Schraubendruckfeder Verbindung mit dem Wärmeleitblock 12 haben.The spray nozzle is in turn held in a plastic cap 11 which is pushed over the nozzle body 1. In order to be able to avoid freezing of the overall arrangement, a heat-conducting block 12 is provided within the spray nozzle head, against which a PTC element 13 rests in that a helical compression spring 14 presses this PTC element against a surface 15 of the heat-conducting block 12. The voltage supply to the FIC element follows it via a cable 16 and then via the helical compression spring 14. The other tension sensor can also have a connection to the heat-conducting block 12 via an identical helical compression spring, not shown.

Die Zeichnung läßt erkennen, daß die Zuführleitung 9 durch einen Teil des Wärmeleitblockes 12 gebildet ist und der Wärmeleitblock 12 mit einem nach oben gerichteten Fortsatz 17 bis nahe zur Spritzdüse 10 reicht. Dadurch wird die Wärme vom PTC-Element 13 bis nahe zur Spritzdüse 10 geführt. Die Aufheizung des Rückschlagventils 4 erfolgt dadurch, daß die Blattfeder 6 auf der Ventilklappe 5 aufliegt und zwischen Ventilklappe 5 und dem Wärmeleithlock 12 eingespannt ist, so daß sie die Wärme aus dem Wärmeleitblock 12 zur Ventilklappe 5 zu leiten vermag.The drawing shows that the feed line 9 is formed by a part of the heat-conducting block 12 and the heat-conducting block 12 extends with an upwardly directed extension 17 close to the spray nozzle 10. As a result, the heat is conducted from the PTC element 13 to close to the spray nozzle 10. The check valve 4 is heated in that the leaf spring 6 rests on the valve flap 5 and is clamped between the valve flap 5 and the heat conducting block 12 so that it can conduct the heat from the heat conducting block 12 to the valve flap 5.

Für den Anschlußstutzen 3 kann ein dem Rückschlagventil 4 entsprechendes Rückschlagventil im Spritzdüsenkörper vorgesehen sein, welches ebenfalls über den Wärmeleitblock 12 beheizbar ist.For the connection piece 3, a check valve corresponding to the check valve 4 can be provided in the spray nozzle body, which is also heatable via the heat-conducting block 12.
